40–60% of Vehicle Development Delays Can Be Prevented at Design Stage: Vector Consulting Report

Indian auto OEMs have invested heavily in digital product development tools over the past five years, 93% have committed Rs 50 crore or more, yet vehicle launches across the industry continue to run 9-15 months behind schedule on average, with complex programmes slipping 18-24 months, according to a new white paper by Vector Consulting Group.

Titled ‘The Race is Won in the Pit Stop: 3D Maturity and the Future of New Product Development in Auto OEMs,’ the paper is based on a survey of 57 senior executives, 41 OEM CXOs and 16 Tier-1 supplier leaders across the two-wheeler, passenger vehicle, commercial vehicle and EV segments.

The white paper argues that automotive development delays are created much earlier than they become visible. While most organisations focus on resolving issues during physical builds, 34-47% of total programme delay surfaces only after tooled-up and pilot builds begin. The research finds that the majority of these issues originate during the design stage, where fitment, manufacturability, and serviceability problems can be identified and resolved in hours rather than months, and at a fraction of the cost.

The study found that 39% of programmes reach the start of production with fitment, serviceability, or quality issues still unresolved. Even where OEMs have introduced hard quality gates to prevent this, 47% of respondents admit these gates are relaxed under launch pressure. Survey respondents estimate that 40-60% of build-stage issues could have been prevented through stronger validation and collaboration at the design stage.

“Indian OEMs have not under-invested in fixing delays; they have invested in the wrong place. Our research shows that by the time problems surface on the shop floor, the opportunity to solve them quickly has already passed. Hard gates are relaxed under launch pressure, and nearly four in ten programmes still reach launch with unresolved issues. The real lever is upstream: identifying and resolving issues digitally, long before the first physical build begins,” said Ravindra Patki, Managing Partner, Vector Consulting Group.

The white paper introduces the concept of 3D maturity and outlines five enablers to help automotive manufacturers close this gap, including capping concurrent development programmes to protect specialist bandwidth (98% respondent agreement) and instituting an empowered, Chief-Engineer-style technical leader with the authority to resolve cross-functional conflicts before designs are released (100% agreement). Together, these measures aim to reduce development delays, improve engineering productivity, strengthen supplier collaboration, and accelerate time-to-market.
